IMPROVEMENT IN PUMPS.'

Specification forming part of Letters Patent No. 220,858, dated October21, 1879 application filed September 6, 1879.

part of this specication, and to the letters.

and gures of reference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal verticalsection of my improved pump, and Fig. 2 is a side view of the same.

This invention has relation to improvements in submerged pumps.

The object of the invention is to improve this class ot' pumpsgenerally, but more especially to devise means for dispensing withpiston-packings, which, from their liability to leak when under water,are objectionable.

The nature of the invention will be fully expla-ined hereinafter.

In the annexed drawings, the letter Adesignates the barrel of the pump,having at its lower and upper ends, respectively, the ilanges a a', towhich are secured the corresponding anged ends ot the strainer B and adouble elbow-pipe, B', into the open end of which are inserted thecoupled wooden sections O, leading to the surface. Between the barreland lower end of the elbow is clamped a seat, b, having anupwardly-opening valve, b.

The strainer B is a closed cylindrical vessel closed at bottom andprovided at its middleupper half with perforations. It is provided onopposite sides with ribs c, in which "are formed grooves c', extendingup through the ange-joints of the strainer cylinder and barrel, theobject of which will be explained hereinafter.

The elbow has a vertical part, d, a horizontal part, d', and a secondvertical part, d2, the object being to throw the part d2 out. of linewith the longitudinal axis of the barrel.

O indicates a U-shaped bail, the lower portion of which is receivedl inthe grooves or guides c', and corresponds in length therewith. The legsof the bail extend above the barrel through the joint-Hanges aforesaid,being slightly spread for the purpose above the strainer, and theirupper ends are connected together above the horizontal part ofthe elbowby a strong arched brace, d, to the apex of which is secured a guidedendwise-movable rod, D, actuated to reciprocate endwise by means of alevenhandle, D', pivoted to the top section, O, above the ground.

Rod D may be composed of a number of coupled sections, and is guided inits up-anddown movements by suitable eyebolts secured to the lwoodensections aforesaid.

J indicates an open seat having in its upper end, above the openings fin its sides, an upwardly opening valve, g. This seat ts snugly in thelower end of the barrel, extends down into the strainer, and isconnected to lthe lower end of the bail by a stem, h. When the bail isat its lowest point of depressionthat is, nearly in contact with thebottom of the strainer-the upper end of the plunger J g still remainsWithin the lower end of the barrel, and as it forms a tight jointtherewith water can only reach the said barrel through the openings inthe sides of the seat or valve-carrier and through the valve g.

By operating the handle water will be raised in the ordinary manner, anddischarged through the spout.

It will be observed that the pump above described needs no stufng-boxesor other like devices, but yet works perfectly.

What I claim as new, and desire to secure by Letters Patent, is-

1n apump, the combination, with the barrel A, having theupwardly-opening valve b', of the double-elbow pipe B', the strainer B,having inside vertical grooves, c', the bail O, working endwise -in saidgrooves and carry ing the plunger J g', the arched brace d, and lever D,combined, arranged, and operating as set forth.

In testimony that I claim the above I have hereunto subscribed my nameinthe presence of two witnesses.
